Epiphan Networked VGA Grid - Manual (Page 298)

Preservation of source aspect ratio
A new feature, enabled by default, makes sure that the aspect ratio of input signals is preserved when encoded and
streamed. If an input video signal doesn't match the encoding ratio, a matte is applied and bars are visible at the sides
or top and bottom of the encoded stream. The color of the matte is customizable.
Customizable stream background color (matte)
You can select the matte color displayed when a layout results in pillarbox or letterbox effect due to input aspect ratio
preservation or when a multi-view layout has areas with no video.
Personalized stream metadata
Each channel has its own content metadata that you can configure to ensure proper attribution, content description
and copyright information is sent with your audio/video stream.
Mobile and Tablet Features

See Mobile / Tablet Operator Interface .
Discovery of Epiphan devices
Use the new Epiphan Connect application on Android and iOS as an alternative to the desktop based discovery utility.
The application has built-in support for opening the tablet operator interface and can be configured to automatically
open the tablet interface if connected to the Networked VGA Grid by USB.
Mobile tethering
Release 3.11.0 introduces the option to use mobile tethering for recording control, confidence monitoring and mobile
network file transfers. Configure mobile data tethering and turn on automatic file uploads to automatically transfer
files to a remote site using the public mobile network. Alternatively, choose to tether for confidence monitoring and
recording control only.
Configure the Networked VGA Grid to use no mobile data, to use Ethernet normally and switch to mobile data if the
Ethernet becomes unavailable, or to mobile data as the preferred transmission method.
